ARCH-TRUSS BRIDGE HAVING VIBRATION ABSORBING MEAN FOR ARCH STEEL PIPE
The present invention provides an arch-truss bridge having a vibration absorbing unit for an arch steel tube, capable of obtaining fine appearance and ensuring structural stability of a bridge by enabling an arch steel pipe absorbing external force acting on a bridge and alternately transfer the same to slidably move. The arch-truss bridge comprises first and second abutments (12, 16) positioned to be spaced apart from one another at a predetermined distance; a pair of steel tube girders (20) spaced apart from one another at a predetermined interval and having both end portions fixed and coupled to each of the first and second abutments (12, 16); first and second protrusion guide tubes (31, 33) protruding in a direction toward the second abutment (16) to a predetermined length from one side of an upper portion of the first abutment (12) and third and fourth protrusion guide tubes (35, 37) protruding in a direction toward the first abutment (12) to a predetermined length from one side of an upper portion of the second abutment (16); first, second, third, and fourth upper cover plates (41, 43, 45, 47) and first, second, third, and fourth lower cover plates (42, 44, 46, 48) respectively covering upper and lower portions of the first, second, third, and fourth protrusion guide tubes (31, 33, 35, 37); and first phase lower arch steel tubes (51, 53) having both end portions fixed and coupled to the first phase lower cover plates (41, 42) and the third phase lower cover plates (45, 46) and second phase lower arch steel pies (55, 57) having both end portions fixed and coupled to the second phase lower cover plates (43, 44) and the fourth phase lower cover plates (47, 48); and a plurality of connection steel tubes (62) positioned to be spaced apart from one another at a predetermined interval and respectively connecting the first and second upper arch steel tubes (51, 55) and the first and second lower arch steel tubes (53, 57).
